reduced set of alternatives in package mlogit
code? example data? We can only guess based on your vague post. "PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code." Moreover, this sounds like a statistical question, not a question about R programming, and so might be more appropriate for a statistical list like stats.stackexchange.com .

I'm trying to estimate a multinomial logit model but in some choices only alternatives from a subset of all possible alternatives can be chosen.
At the moment I get around it by creating "dummy" variables to mean the alternative is not available and let it estimate this coefficient as highly negative. Is there a better way to do it?
